            Bug ID: 147590
           Summary: The JSONP parser incorrectly parsers -0 as +0.
    Classification: Unclassified
           Product: WebKit
           Version: 528+ (Nightly build)
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: keith_miller at apple.com

Running x = -0 on the jsc command line causes x to be set to 0 rather than -0. This is due to an issue in the JSONP parser which stores the accumulator variable while reading the number token as an int rather than a double.
